CAMS_73 Greenhouse-gas fluxes

Tender description

As the Entrusted Entity for implementing the Copernicus Atmosphere Monitoring Service (CAMS), ECMWF issued an Invitation to Tender (ITT) to provide quantitative estimates of natural and anthropogenic surface fluxes of greenhouse gases, which are key drivers of the earth’s climate evolution. Ground-based and satellite remotesensing observations allow these to be monitored. This ITT is for extending the time-series of CH4, CO2 and N2O surface flux fields, both forwards and backwards (as far as possible) in time, while maintaining their quality at the highest international standard. Periodically, the successful Tenderer will reprocess the whole period in order to reflect improvements in spatial resolution as well as in modelling and data assimilation techniques used for the atmospheric flux inversions. The documentation of associated errors and comparison with independent observations as well as with main competing international products will also form part of the activities. A proven track record in the field of atmospheric flux inversions will be among the main criteria for selection. Portal instructions: In order to allow potential bidders to get a better understanding of the service tendered before committing to it, some of the ITT documents are accessible under the ‘Attachments’ box at bottom right of this page. The full set of ITT documents and relevant questions are only accessible by registering an interest in this opportunity (see the 'Expression of interest window' at top right). Please refer initially to the ‘ECMWF eProcurement Portal Guidance for suppliers’ file in the Attachments box as this document will help you navigate the portal and locate the necessary information in order to submit a proposal. Please note that the contact email address shown under 'Contact details' is not monitored, and any messages sent to this email address will not be attended to. Questions / clarifications concerning this ITT must be submitted via the Messaging area of the ITT, which can be accessed through the My Activities page of the Portal once you have logged-in and registered your interest in this opportunity.
